Solder Mask

[Jon Slaughter]

How is the solder mask applied? That is, how do they avoid applying the
resist to a pad? Similar to etching(using the photomask somehow) or applying
a physical mask(like taping over the pads)?

It's silk-screened on using artwork designed by the layout person.

Hope This Helps!

If you would stop trying to use a wrench for a hammer,
life would be a lot simpler.
Get yourself a proper ECAD and you will find layers called RESIST.

This is free, it's bootable, and it contains 2 ECADs:
